Interactive exploration of near-infrared spectral signatures across crop types

Understanding Spectral Data

Near-infrared (NIR) spectroscopy is a non-destructive technique that measures how plant tissues absorb and reflect light at different wavelengths. Each crop has a unique "spectral fingerprint" determined by its biochemical composition.

From Spectra to Predictions

This spectral data forms the foundation of our machine learning models:

The ability to predict chemical composition from spectral data enables rapid, non-destructive assessment of crop nitrogen status in the field.
